Malleable Iron 529 Extension Pieces M/F NPT Thread

Products Details

Malleable Iron 529 Extension Pieces M/F. The function of socket M/F is same as the entire socket to connect the pipes or fittings. The difference is the ends of the pipe are different. The socket M/F is with NPT threaded, both ends are American standard tamper threaded and can only suitable to American pipes. The minimum size of the socket is 1/2″ (DN15) and the maxium size of the socket is 2″ (DN50)

How to distinguish British standard threads from American standard threads,

BSP is British Standard Pipe. BSP threads include two types, one is a tapered thread and the other is a pillar thread.

BSP Taper Thread (BSPT): This is a tapered thread, similar to NPT thread, which has a gradually tapering taper and is used for pipe connections, relying on the shape of the thread to form a seal when tightened.

BSP Pillar Thread (BSPP): This is a parallel thread, also known as cylindrical thread, where the diameter of the thread remains consistent throughout its length. BSPP threads are commonly used for pipes and fittings that require sealing and connections.

Therefore, the BSP thread system covers both tapered and column thread types. Different BSP threads are suitable for different types of connections and applications.

What is BSP?

NPT: National pipe thread, full name: American National Standard Taper Pipe Thread. It is an American tapered thread standard commonly used in general industrial components. It is often used for sealing industrial components that cannot or do not require any seals, and have a wide range of applications. It can be used in external threaded and internal threaded.

NPS: National pipe straight, full name: American National Standard Straight Pipe Thread. It is an American parallel thread standard commonly used in general industrial components. For rigidity requirements, seals need to be used; It can only be internal threaded.
